- If you see the error message "Unable to load file" and the game crashes, the installation is usually defective. This could be due to defective RAM or defective hardware.
- Defective RAM is also most likely the source of reported, unreproducible crashes. There are various tools available to check the RAM, such as Microsoft's "Windows Memory Diagnostic."
- The ATI Tray Tools utility, which is not an ATI product, could cause the game to crash when it starts. Please close the ATI Tray Tools before opening Secret Files: Tunguska.
